EGG-BEATER.

Specification of Letters Patent No. 31,663, dated March I2, 1861. v

' a screw spindle furnished with wire breakers or dashers, and operated by a reciprocating nut, and my improvement consists of a tube with a screw thread, a nut, and wire beaters or dashers in combination with an internal rod having at the end a disk or button, the whole being constructed and arranged substantially as described hereafter for the purpose of obviating certain defects experienced in this class of instruments, as hitherto constructed.

In order to enable others, to make and use my invention, I will now proceed to describe its construction and operation.

On reference to the accompanying drawing, which forms a part of this specification, Figure 1 is an elevation, partly in section, of my improved egg beater. Fig. 2 a transverse section on the line 1. 2 Fig. 1. Fig. 3 an inverted plan View. Fig. 4 a detached view of part of the instrument, and, Fig. 5 a modification of part of my improved beater.

Similar letters refer to similar parts throughout the several views.

B is a tube around which are coiled and secured in a spiral direction, any convenient number of wires C C (three being used in the present instance) these wires forming the thread of a screw of which D is the nut, the latter consisting of a round or other suitably shaped piece of wood, or other material with a hole large enough to fit freely over the tube and its wire threads, a pin a being screwed into this nut, and the point of this pin penetrating into the space between the spiral wires as seen in Fig. 2.

The wires are spread out and bent at their lower ends so as to form the three breakers or dashers b b b all of which are firmly secured to the tube at the lower end of the same.

Through this .tube 13 passes a rod G, which is secured at the top to the handle H and at the bottom to a short tube (Z, which forms a part of the disk or button 6. The length of the tube B is such, compared with the distance between the lower end of the handle H and the top of the short tube (Z, that the said tube B can have a slight longitudinal play on the rod G.

In place of the spiral wires G, C, I in some instances lap around the tube spirally, a strip of metal as seen in Fig. 5 so as to form a spiral groove for receiving the point of the set screw (4. The eggs having been deposited in a suitable vessel the lower end of the above described instrument is placed in the vessel on the bottom of which the button 6 rests; The operator holding the handle H in his right hand moves the nut D up and down with his left hand thereby imparting a rapid rotary motion first in one and then in the other direction to the tube.

and its beaters which rapidly reduce the eggs to the desired consistency.

I am aware that an instrument composed of a screw spindle with breakers or dashers and operated by a reciprocating nut has been heretofore used for beating eggs, the screw spindle however turned in the handle and at the point where it rested on the bottom of the vessel, in consequence of which two difficulties in the way of effectually using the instrument presented themselves. Firstly, the instrument cannot be held steadily in its proper position owing to the constant turningof the point on the bottom of the vessel; secondly, a slight pressure on the handle induces so much friction as to interfere with the easy working of the instrument.

In my improved egg beater the base, consisting of the button 6, which rests on the bottom of the vessel, is stationary and therefore has no tendency to slip and as the pressure imparted to it is sustained by the stationary rod and not by the tube the latter is free to rotate under any pressure to which the instrument may be necessarily subjected.

I do not desire to claim broadly an egg beater composed of wire dashers a screw threaded shaft and nut as such a device has been heretofore used but I claim as my invention and desire to se- In testimony whereof, I have signed my cure by Letters Patent name to this specification, in the presence of 10 The tube B, its screw thread, the nut D two subscribing Witnesses. and beaters or dashers b in combination 5 With the internal rod G and its disk or but- WALTER HART ton e the Whole being constructed and ar- Witnesses: ranged substantially as and for the pur- HENRY HowsoN, pose herein set forth.
